Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 15 Issued at 2200Z on 15 Jan 2016

IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C2 event observed at 15/0239Z from Region 2480 (N04W52). There are currently 3 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low with a chance for a C-class flares on days one, two, and three (16 Jan, 17 Jan, 18 Jan).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 497 km/s at 14/2302Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 2577 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet levels on days one and two (16 Jan, 17 Jan) and quiet to unsettled levels on day three (18 Jan).
